Area of Science:

  • Oncology
  • Pathology

Background:

  • Extraskeletal Ewing sarcoma (EES) is a rare malignant tumor.
  • Typically, EES presents as a localized swelling in soft tissues.

Observation:

  • A patient presented with a retroperitoneal extraskeletal Ewing sarcoma.
  • The primary symptom was massive tumor embolism to the pulmonary vasculature.

Findings:

  • This is the first reported case of EES presenting with pulmonary tumor embolism.
  • The tumor originated in the retroperitoneum.

Implications:

  • This presentation expands the known clinical spectrum of extraskeletal Ewing sarcoma.
  • Highlights the importance of considering rare presentations in differential diagnosis for pulmonary embolism.
